Pathophysiology Exam | Questions and Verified ANSWERs with Rationales| 100% Correct- Maryville Is it true that a eukaryotic cell

• is smaller than a prokaryotic cell.
• Contains structures called organelles.
• Lacks a well-defined nucleus.
• Does not contain histones.

ANSWER: b

ANSWER: Eukaryotic cells contain organelles, unlike

prokaryotes. They are larger, have a defined nucleus, and contain histones, making B the correct statement.

The function of a histone found in a eukaryote cell focuses on

cellular:

• division
• Movement
• Activities

• DNA folding

ANSWER: d

ANSWER: Histones are proteins around which DNA coils in

chromatin, aiding in DNA folding and packaging.

An organelle that is responsible for the metabolism of cellular

energy is referred to as an:

• golgi complex
• mitochondrion
• endoplasmic reticulum
• nucleolus

Which statement best describes a desmosome?

• A barrier to diffusion.
• Holds cells together by continuous bands.
• A communicating tunnel.
• Function as a zona occludens.

ANSWER: b

ANSWER: Desmosomes are anchoring junctions that hold cells

together via continuous bands, providing mechanical strength.

Which statement describes a function of a second messenger?

• Binds the membrane-bound receptors via a ligand.
• Triggers a cascade of intracellular events.
• Opens specific channels in the cell membrane.
• Blocks a membrane-bound receptor signal.

ANSWER: b

ANSWER: Second messengers, like cAMP, trigger intracellular

signaling cascades after receptor activation.

Which statement is correct regarding cellular energy?

• Glycolysis is the building of sugar molecules.
• Oxidative cellular metabolism is a single reaction making

adenosine triphosphate (ATP)

• Oxidative phosphorylation occurs in the mitochondria.
• Anaerobic glycolysis occurs in the presence of oxygen.

ANSWER: c

ANSWER: Oxidative phosphorylation, producing ATP, occurs

in mitochondria; other options mischaracterize processes.

Movement of a solute molecule from an area of high

concentration to an area of low concentration is called:

• Diffusion
• Filtration
